Throughout the Corps more than 4,000-mile journey, Captains Lewis and Clark recorded 178 plants and 122 animals not previously known to science. Lewis recorded and pressed and preserved some 240 different plant species and brought them back to Washington, along with hundreds of animal and bird skins and skeletons.
Approximately 3,200 species of vascular plants have been identified that are native to Canada. Botanists estimate that we have about 150 endemic species (those found only found in Canada). In 1990 the Canadian Museum of Nature classified about 1000 of our native plants as rare.hile many of these rare plants are more common elsewhere in North America, the biodiversity of our natural habitats in Canada depends on survival of plant populations adapted to our climate and environmental conditions.
